• Direct measurement of ions without costly sample conditioning or transport
• Simple immersion-mount installation—attaches directly to basin rim in a single assembly
• Measures 24"L x 4.4"Dia with 49"L cable

ISEmax CAS40D Memosens digital interface ion selective electrodes use the potentiometric method to measure ammonium, nitrate, potassium and chloride. Measured values are converted to digital interference-free signals compatible with any Endress+Hauser Memosens controller. Use these electrodes in nitrification and denitrification processes in wastewater applications, and in aeration systems to help reduce power consumption.

This assembly includes pH, temperature and ammonium electrodes. Since elevated and fluctuating levels of potassium and chloride can cause interference, electrodes are also available with potassium and chloride compensation (see stock # 21170 and 21172). All electrodes are easy to maintain. Simply replace the rugged membrane cap every six months—no reagents needed! Each electrode assembly features a tubing connection; external air supply can be connected for periodic in-service automatic cleaning.
